Is this Gerd?

I have been having breathing trouble, constant clearing of throat,hoarseness, etc. I am trying to figure out what this is! Can gerd cause you to have trouble breathing?

I believe I have Gerd because my stomach burns a lot, but I never have acid come up my throat, and I never have a sore throat.I took nexium for 2 months, didn't help.

I felt pretty icky this morning as usual, I laid down for a liitle while because I felt the tightness in my chest, after just about 30 minutes I get this sensation in my throat like its closing or something and CANNOT clear my throat. It sort of feels like if I can clear it then I could breathe.
